To balance the system by design we must increase the air flow rate in Section 2 to bring it up to the higher pressure loss of Section 1. To correct the air flow rate for Section 2 use the Fan Laws: Q 2 new = Q 2 old * (P t loss 2 new/ P t loss 2 old)1/2. Q 2 new = 3000 * (1.165/0.93)1/2 = 3357 CFM. Section 3.

Axial fans, as the name implies, move an airstream along the axis of the fan. The air is pressurized by the aerodynamic lift generated by the fan blades, much like a propeller and an airplane wing. Although they can sometimes be used interchange-ably with centrifugal fans, axial fans are commonly used in "clean air," low-pressure, high-volume

The factor of 102 is used to convert mmWC into pascals because the formula for the static fan efficiency in SI units is;-Static Fan Efficiency = Volume (m3/s) * Pressure gain (Pa) / Power input (W) * 100. But, if the pressure is measured in mmWC instead of Pascals and Power is expressed in kW, the formula can be derived as follows;-1 mmWC = 9.81Pa
